lpplication filed October 22. 1919. Serial No. 332,474.

To all whom it may concern:

Be it known that I, THOMAS NATHAN RUssELL, a citizen of the United States, residing in Chica o, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

The invention relates to car roofs wherein the metal roof sheets are formed with interengaging flanges so as to form a capped seam without the presence or use of a special separate seam cap, and wherein the roof sheets and scams thus formed are held down to the car roof without the necessity of employing any separate special seam clip. In dispensing with these seam clips the construction is simplified and made more economical, there are no seam clips to be knocked 0E by side blows in collisions or other accidents, and the repair of the roof by substituting new sheets is rendered easier and quicker.

With such objects in view, as well as other advantages which may be incident to the use of the improvements. the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical eflect. without limiting the improvements. ,in their useful applications. to the particular constructions which. for the purpose of explanation, have been made the subject of illustration.

In the said drawings V Figure 1 is a vertical section of a portion .of the roof at the caves of the same. the

section being taken transversely to the side late. i i p Fig. 2 is a side elevation of a portion of the ridge of the roof. the same being partly in section on a vertical plane longitudinal of the car.

Fig. 3 is a perspective view of a portion of the eaves flashing. l

, Fig. t is a perspective new ofa portion of the eaves hookstrip.

Fig. 5. is a perspective view of the eaves end of a roof sheet seam and contiguous parts.

Fig. 6 is a plan of a corner portion of a roof sheet before the same is bent into the operative form shown in the other figures.

Referring to the drawings, the roof frame is or may be of a usual construction, comprising side lates 2, one of which is shown in Fig. 1. .n this figure are also shown portions of the side sheathing 3, the top sheathing 4, and the side fascia 5.

Referring first to the means whereby the eaves ends and seams of the roof sheets 1 are confined down upon the top sheathing 4. 6 is an eaves hook strip which is provided with a vertical flange 7 securely attached to the frame of the car. Each eaves hook strip is formed in one or more sections, as may be convenient, extending longitudinally of the car from end to end of the same, and the attachment of the flange 7 is conveniently accomplished by locating it against the said sheathings 3 and 4 and under the fascia 5. and nails 8 may be driven through the fascia. flange 7. side sheathing. and into the side plate 2. The sheet-securing portion of the hook strip is located in a recess 9 formed. therefor in the top of the sheathing 4 and is formed at its top with an outwardly extending hook element 10. The roof sheet 1 is formed with a corresponding hook element 11 which extends inward at the under side of the roof sheet and interengages with the hook element 10. as shown in Fig. 1. This engagement is sufficiently loose to allow to the roof sheet some horizontal play without becoming bent or strained. and without straining the hook strip 6. 12 is an eaves flashing extending over the fascia and into the said loose seam. being interposed between the roof sheet hook 11 and the lower portion of the hook strip. The arrangement is such that this flashing does not interfere with the looseness of the seam and it incloses any ioint or joints through which leakage might otherflange being inturned to overhang the margin of the sheet, and the other side of the sheet is formed with an upstanding flangem is formed at one side with an s awning i hook flange 13 of inverted U-shape, thesald of inverted U shape, which is out-turned away from the margin of the sheet and is provided with a terminal upturned hook element 15. T e construction is such that the sheets may e slid endwise one relative to another so that the upstanding hook flange 13 will be inclosed by the upstanding flange 14 of the next sheet, the hook element 15 engaging under and around the edge of the depending element of the flange 13 so as to prevent any disengagement of the two seam elements from each other excepting by longitudinal sliding.

The flange 14 is formed with an end plate 16 which has the shape of the end of the roof sheet side seam and may be bent into a crosswise position (Fig. 5) so as to entirely close the eaves end of the described seam. This end plate also acts as a stop to hold the inclosed roof sheet from any sliding movement toward the eaves relative to the inclosing roof sheet.

By the use of this means for closing the end o-f'the seam, cooperating with the hooked engagement of the eaves ends of the roof sheets with the frame of the car, by means of the hook strip 6, I am enabled to dis pense with all seam clips at the eaves of the car without impairing the security of the roof sheets ortheir upstanding seams, and seam caps are alsodispensed with.

What is claimed is 1 In a car roof,-the combination of a roof frame, a top sheathing carried thereby,- roof sheets having upstanding hooked side flanges, the flange of one roof sheet embracing the flange of the other roof sheet and said flanges having a hooked interengagement, the exterior flange being formed with an end plate which closes the eaves end of the seam and acts as a stop against relative outward movement ofthe sheet whose flange is inclosed and interengaged hook elements on the roof frame and on the eaves ends of the roof sheets whereby the roof sheets-and seams are held from upward movement.

2. A car roof having incombination, roof sheets formed with upstandingaside flanges of inverted U-shape and interlocked to gather to form a seam,-one of said sheets having means inte al therewith-for closing the eaves endo the seam and for holding the: inclosed roof sheet fI'OlIlrOlltWEtId sliding relative to the inelosing roof sheet, and meansjor loosely confining the eaves ends ofr the roof sheets against upward movement and allowing some horizontal movement thereof-,whereby the roof sheet side seams are alsoheldfrom u wardmove ment at their eaves ends wit out the use ofa seam clip.

a 3' A car roqf'hay-ingin combinatjom roof he tomes .i of inverted U-shap'e and aving 1100 s with upstandin ,si'de flan s.

whereby said flanges are interlocked tegether to form a seam, the exterior of said inter locked flanges having means integral therewith for closing the eaves end' of the seam and for holding the inclosed roof sheet from outward sliding relative to the ininclosing roof sheet, and means for loosely confining the eaves ends of the roof sheets against upward movement and allowing some horizontal movement thereof, whereby the roof sheet side seams are also held from upward movement at their eaves ends without the use of a seam clip;

4. In a car roof, the combination of a roof frame, a top sheathing carried thereby, roof sheets having Upstandingout-turned an'd'i'nturned hooked side flanges of inverted U- shape, the out-turned flange of one roof sheet embracing the inturned flange of the other roof sheet and said flanges having a hooked interengage'ment, the exterior flange being formed with an end plate which closes the eaves end of the'seam and acts as a stop against relative outward movement of the sheet whose flange is inclosed, and interengaged hook elements on the roof frame and on the eaves ends of the roof sheets whereby the roof sheets and-seams are held from upward movement.

5. In a carroof, the combination of a roof frame, a top'sheathingbarried thereby, roof sheets having upstanding hooked side flanges, the flange of oneroof' sheet ein'biacmg the flange of the other roof sheet and said flanges having a hooked interengagement. the exterior flange being formed with an end plate which closes the eaves end of the seam and acts as a stop against relative outward movement of the sheet whose flange is inelosed, and interengaged hook elements on the roof frame and on the eaves ends of the roof sheets comprising hook strips on said frame and hooks formed on the roof sheets, whereby the roof sheets and seams are held from upward movement.

6; A car roof having in combination; roof sheets formed with upstanding side flanges of inverted 'U-shape and interlocked to gether to form, rarseam, one of said sheets having means integral therewith for closing the eaves end of the seam. and for holding the inclosed roof sheet from outward sliding relative to'the inelosing roof sheet 'and an eaves hook stri ,fixed on the frame and corresponding hoo s on the roof sheets iior loosely confining the eavesends of-tl1e-roof sheets against upward movement and a1; lowing some horizontal movement thereof, whereby the roof sheet side seams are also held from upward movement attheir' eaves ends without the use of a s am clip.

7. In a car roof, the corn ination of a noof frame, a top sheathing carried thereb' roof sheets havin upstanding hooked (side ing the flange of the other roof sheet and said flanges havin a hooked interengagement, the exterior ange being formed with an end plate which closes the eaves end of the seam and acts as a stop against relative outward movement of the sheet whose flange is inclosed, said end plate being integral with one side of said exterior flange and being formed with a narrow rounded upper end and a wider lower end and being bent at substantially right angles to said flange, and interengaged hook elements on the roof frame and on the eaves ends of the roof sheets whereby the roof sheets and seams are 15 held from upward movement.

8. A roof sheet for metal ca! roofs, em bodying, a sheet having an upwardly and inwardly rebent flange along one side and an upwardly and outwardly rebent flange along the opposite side adapted to inclose and interengage with the upwardly and inwardly rebent flange of an adjacent roof sheet, and having an end flap bent over against the eaves end of the aforesaid upwardly and outwardly rebent flan e to close the eaves end of the interengage flanging of adjacent roof sheets and to act as a stop against relative outward movement of the sheet whose flange is inclosed, substantially as specified.

In testimony whereof I have hereunto set my hand.
